4K Comparison Methodology

The main goal of this report it the presentation of a comparative evaluation of the quality of new HEVC codecs and codecs of other standards using objective measures of assessment. The comparison is done using presets provided by the developers of each codec. Nevertheless, we requir all codecs to satisfy minimum speed requirement on the particular use case.

For this platform we considered four key use cases with different speed requirements:

  • Fast: UHD, 30fps
  • Universal: UHD, 1fps
  • Fast 10bit: UHD-10bit, 30fps
  • Universal 10bit: UHD-10bit, 1fps

12 video sequences at 4K resolution were used for tests: 8 video sequences had 8-bit color depth and 4 video sequences had 10-bit color depth. Note: we used technically 10-bit videos for evaluation, but the colours in the videos themselves do not utilize wide luminance range (they are not HDR).

Brief methodology review is given in the presentation:
